GENERATOR.

T 0 all whom it may concern:

Be it known that I, JOSEPH J. Wnxim, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Generators, of which the following is -a specification.

My invention relates to certain new and useful improvements in generators, and is fully described and explained in the speci fication and shown in the accompanying drawings, in which:

Figure 1 is an elevation of my improved device; Fig. 2, a vertical section therethrough; Fig. 3, a plan view of the upper burner, and Fig. 4: a plan of the lower burner.

Referring to the drawings-A 'is a supply tube adapted to be connected with a source of gasolene-supply or of other liquid hydrocarbon. This pipe is connected by a union A with a valve-fitting B. This valve-fitting, it is to be noted, has a central opening 6 extending upward from the bottom, a transverse opening controlled by a needlevalve B, and a vertical opening Z2 offset laterally with respect to the opening b, and having communication with the opening 6 The upper end of the valve-fitting B is internally screw-threaded and receives, and furnishes support for, a hollow T-fitting G, into which the liquid gasolene can pass at the bottom and from the two horizontal arms of which it can issue laterally in the form of vapor. Each arm of the T-fitting C, has a valve-fitting D. The valve-fittings D are made in the form of crosses, one horizontal arm of which is connected to the corresponding horizontal arm of the T-fitting C. The opposite horizontal arm of the valve-fitting D is inclosed by a perforated cap D", by means of which shouldered conical plugs (Z are driven into contact with the openings in the said horizontal arms of the valve-fitting whereby to close the same. Thus by the removal of the cap D on the two valve fittings, a horizontal opening of large diameter is exposed extending entirely through the T-fitting C, whereby the vaporizing portion of the device can readily be cleaned. The upwardly projecting legs of the valve fittings D are provided with nozzles which are adapted to be opened and closed by needle-valves D threaded support Specification of Letters Patent.

for which is provided by downwardly projecting legs of the valve-fittings D.

The upwardly extending legs of the valvefittings D give support for air-intake chambers E. Each of these chambers is made in the form of a horizontal cylinder, closed at one end and open at the other, the open ends being turned outward. The chambers are provided with small bosses on their upper and lower surfaces, the lower boss to afford connection with the upwardly extending leg D of the corresponding valve-fitting D, and the upwardly extending boss serving for the passage of mixing-pipes F. The mixing-pipes F are surrounded by spreaders G, and their upper ends are secured to gas pipes H, between which and the intakechambers the spreaders Gr are disposed in the manner illustrated. The gas-pipes H are threaded at their upper ends for the reception of eduction pipes and are provided on their sides adjacent to their upper ends with small bosses which receive inwardly and downwardly projecting elbows h, 71 on the two gas pipes, respectively. The vertical leg of the T-fitting C, is surrounded by two annular burners I and J, respectively, the burner I being smaller than the burner J and beneath the same. Both of the burners are made in the form of hollow castings having slots cut in their upper surfaces for the egress of combustible vapor. The lower burner, I, is secured by set-screws to the T-fitting C, and the upper burner is secured by braces or struts i thereto.

The burner I is connected by a pipe I with the elbow it connected to the gas-pipe H on one side and the burner J is connected to the corresponding elbow h on the opposite gas-pipe H The operation of my device is as follows: The liquid fuel passes up through the passages b, 6 b in the valve-fitting B, and through the T-fitting C, where it becomes intensely heated, the heat being intensified by means of the heat collecting shield K of hollow-conical form, supported andcarried by the upper end of the T-fitting C, and provided with openings 70 for the egress of burned vapor. In the course of its passage through the T-fitting C, the liquid is completely vaporized, and passes, in the form of gas, out of the nozzles D thence through intake-cylinders E and into the mixing-tubes F. During its passage through said mixingtubes, it is completely intermingled with the air drawn in in the manner shown and is rendered suitable for burning. portion of the mixture then passes through the tubes I and J to the two burners where it is burned, and the remaining vapor passes up through the gas-egress pipes where it can be used in any manner desired, as for instance, in lighting.

The present device is exceedingly desir able by reason of its simplicity, compact ness, and the large amount of vapor which can be generated with it. It has heretofore been the practice to adopt a separate generator-tube for each gas pipe of the size used in connection with my construction, whereas, in the present device, by the means adopted, it is possible to concentrate suflicient heat upon one vaporized to supply gas for two gas-pipes without substantially increasing the size of the apparatus. This is particularly advantageous when supplying vapor to portable lamps, such as are used in circuses, and the like, where an immense amount of gas must be generated, and where the floor space is at a great premium. In such installations my generator is mounted upon the top of a single tank containing fuel under pressure, and it will supply gas, without difliculty, to as many lights as can with convenience be piped to a single point.

I realize that considerable variation is possible in the details of construction of my improved device, without departing from the spirit of my invention, and I do not intend therefore, to limit myself to the specific form herein shown and described.

That I regard as new and desire to secure by Letters Patent is- 1. In a device of the character described, a T-shaped vaporizer, means for supplying liquid fuel to the vertical leg thereof, two

burners encircling said vaporizer and arranged one above the other, two mixingtubes each of whlch communicates with one A certain of the lateral arms of the vaporizer, and independent means for conducting gaseous fuel from the mixing tubes to each one of the burners.

2. In a device of the character described, the combination with a T-shaped vaporizer, of means for supplying liquid fuel to the vertical leg thereof, two burners encircling said vaporizer, two mixing-tubes each of which communicates with one of the lateral arms of the vaporizer, independent means for conducting gaseous fuel from the mixing tubes to each one of the burners, and means carried by each one of the lateral arms of the vaporizer to cut off the flow of fuel from such arm to the mixing tube with which it communicates.

3. I11 a device of the character described, the combination with a liquid fuel supply pipe of a vaporizer mount-ed thereon and comprising a vertical portion with lateral arms extending therefrom, two burners in superposed relation one with the other and encircling said vaporizer, a mixing chamber carried by and communicating with each end of the lateral arms of the vaporizer, and independent gaseous fuel-conducting connections between each one of the mixing chambers and the respective burners.

4. In a device of the character described, the combination with a liquid fuel supply pipe, of a T-shaped Vaporizer having its vertical portion connected thereto, two burners encircling said vaporizer and arranged one above the other whereby the upper burner is superheated by the lower one of the pair, valved connections on the ends of the lateral arms of the vaporizer, vertically ex-' connections, and pipes connecting one of each of said mixing chambers to one of said burners.
